What are some of your recommendations for home wireless signal boosters/extenders ?

My router is in my downstairs bedroom. I have a garage office where the signal is weak.
I was using an older Linksys range extender stand alone unit sitting on a refrigerator in
my garage closer to the garage/home wall. The unit died and im looking for a replacement.

Any suggestions ? I want it to be stand alone unit which picks up the router signal, amplifies
it and sends it out to my garage office pc antenna.

A close friend had a problem of insufficient wi-fi signal at his second home, out in the country, getting an adequate wi-fi signal between the main house to a guest cottage. I researched repeaters, this one had high recommendations, he bought it and I installed it for him. Works well

I prefer to use either a router that has repeater functionality (a lot of new ones do) or an older router which can sometimes turn it into a repeater with free firmware like WW-DRT or Tomato. The router can sometimes be cheaper than a dedicated repeater (free if you have an old one) and can also be used as a wired switch to connect additional devices (printers, disks, AV recievers, game consoles, etc) that need a wired connection.
